The National Day of Remembrance for Victims of the German Nazi Concentration Camps and Death Camps  is a Polish holiday celebrated on 14 June. It was passed on 8 June 2006 by the Sejm of the Republic of Poland on the 66th anniversary of the arrival of the first mass transport of prisoners to KL Auschwitz. On 14 June 1940, the Germans sent the first transport of political prisoners consisting of 728 Poles from Tarnów to KL Auschwitz; among them was a small group of Polish Jews. This day is considered to have marked the beginning of the camp's operation.
